Your body needs coenzyme Q10 to fuel cell function. CoQ10 has been studied for its effects on chronic conditions including cancer, high blood pressure and heart disorders. It may improve your overall heart health, though it may not necessarily improve atrial fibrillation symptoms. Talk to your doctor before trying CoQ10.
Atrial Fibrillation
Atrial fibrillation occurs when the heart's upper chambers get out of rhythm, causing a rapid and irregular heart rate. Some people get atrial fibrillation only occasionally, although for many it is a chronic condition. If your heart goes into atrial fibrillation, you may feel palpitations and experience weakness or difficulty catching your breath. Atrial fibrillation has a number of possible causes, including genetics, alcohol binges, thyroid problems and high blood pressure. Anyone with heart disease has a higher risk of developing atrial fibrillation, according to MayoClinic.com.
CoQ10
CoQ10 is short for coenzyme Q10, an enzyme found naturally in most people's cells. CoQ10 plays a role in cell energy production, creating a substance called ATP which all cells need to function. Like many other vitamins and supplements, CoQ10 also has antioxidant properties. In addition to contributing to a healthy immune system, the University of Maryland Medical Center reports the antioxidant properties of CoQ10 may prevent some disease-causing effects of free radicals. Free radicals are substances that roam the body and may contribute to many chronic conditions, including heart disease.
CoQ10 and Heart Disease
There is little direct evidence that CoQ10 can improve atrial fibrillation. Its effects on heart disease in general have been studied, though not extensively. In a 2010 article in "Advances in Healthy Aging," Dr. Isaac Eliaz reports that low levels of CoQ10 have been associated with several types of heart disease. CoQ10 supplementation has reduced the risk of heart failure in several different populations, according to Eliaz. In addition, UMMC reported a reduction in the rates of recurrent heart attacks in those who took the supplement. People who took CoQ10 before heart surgery also had a reduced risk of irregular heartbeats during recovery, according to UMMC. While atrial fibrillation is not mentioned specifically, CoQ10 may reduce some of the associated risk factors.
Considerations
CoQ10 is found naturally in many whole grains and oily fish, though most of the research involves its supplemental form. Getting more CoQ10 in your diet is generally safe, though the supplement comes with a few warnings. It can cause digestive upsets, and may reduce the effectiveness of blood-thinning medications. In addition, CoQ10 is not recommended for children. Adults can take between 30 and 200 mg every day, according to UMMC. You can purchase CoQ10 over the counter; however, do not take CoQ10 without first talking to your doctor.
